The problem is that 7^2 is 7*7, and the same for 8^2. The right answer is the square root of 15, or 3.87
Answer:
x = -9
Step-by-step explanation:
ANGLES IN A TRIANGLE ADD UP TO 180°
50° + 80° = 130°
180° - 130° = 50
x+59 = 50
x = -9
Take the LCM of the three numbers. Since 2 is a multiple of 4, you can ignore the two and just take the LCM of 4 and 3.5. Since 3.5 is a decimal, the LCM is just 3.5*4 which is 14. That is how many minutes after 8:00 they will flash together again.<span />
1) True. In a function, each x value has exactly one y value.
2) False. For example
is a function, but is not linear. It is represented by a parabola.
